Knock $10-20k off the price and put that towards hiring people to clean it. Bundle the house sale with cleaning services for a few years or something. The amount of people willing to deal with it will grow as the price falls, but that's not newsworthy. That's the uncomfortable truth for people wanting to sell.
Not just energy costs - replacements for kitchen/bathroom fittings as they fail, painting/decorating, cleaning, basic maintenance to ensure the place doesn’t fall down, keeping gardens from becoming overgrown, the list goes on.
